lc_get_hive_record_metadata

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description carries the full burden. It only states the action without disclosing any behavioral traits (e.g., read-only nature, required permissions, side effects). The agent has no additional context beyond the function name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise (one sentence). However, it is too minimal for the tool's complexity, lacking parameter explanations and usage context. Conciseness is achieved at the expense of completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With four parameters, no output schema, and no annotations, the description provides minimal context. It does not explain what metadata is returned, how to use the parameters, or how this tool fits with other Hive-related tools. The description is incomplete for an agent to confidently select and invoke the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, yet the description adds no information about any of the four parameters (key, oid, hive_name, partition_key). The agent must guess their meaning from parameter names alone, which is insufficient for correct invocation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Fetch') and the resource ('one Hive record's metadata'). It distinguishes from sibling tools like 'lc_get_hive_record' and 'lc_get_hive_schema' by specifying 'metadata' rather than the record itself or its schema. However, it could be more precise about what constitutes metadata.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as 'lc_get_hive_record' or 'lc_get_hive_schema'. The agent is left to infer usage from the name alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
